Tears (Video)
Tears are necessary to keep our eyes moist and health. This helpful video from the American Academy of Ophthalmology will help answer questions and explain common eye diseases and treatments.
Intraocular Lenses (IOLs) (Video)
IOLs are often necessary following Contract Surgery. This helpful video from the American Academy of Ophthalmology will help answer questions and explain common eye diseases and treatments.

Intraocular Lens (IOL)
Like your eye's natural lens, an IOL helps you see by focusing the light that comes through the cornea and pupil, focusing the light onto the retina. The retina converts the light rays into signals that are sent through the optic nerve to the brain, where they are interpreted as the images we see. Learn more at http://www.geteyesmart.org. -
Monofocal Lens (IOL)
Traditional monofocal lenses focus light entering your eye at a single focal distance. This means you will see best at either far, near, or intermediate distance without glasses, depending on the lens power you select. Most people choose a lens that provides good distance vision without glasses. Learn more at http://www.geteyesmart.org. -
Monofocal Correction Options
Monofocal IOLs provide good vision at one focal distance. With a monofocal IOL set for distance, you will need reading glasses for close-up vision. If you choose a monofocal IOL set for near vision, allowing you to read without glasses, then you will need glasses to see clearly in the distance. Learn more at http://www.geteyesmart.org. -
Multifocal Lens (IOL)
Multifocal intraocular lenses use specially-designed circular focal zones or rings on the surface of the lens. Depending on where the light rays are focused through the different zones or rings, you may be able to focus well at both near and distance.

Accommodative Lens IOL
You may choose to replace your natural lenses with accommodative IOLs after cataract surgery. Accommodative IOLs work with the ciliary muscles to move the IOL forward and backward. This movement of the lens allows the focus to change from near to far, providing good vision up close and far away. Learn more at http://www.geteyesmart.org. -
Toric Lens IOL
Toric IOLs are monofocal lens implants with astigmatism correction built in. They may not completely eliminate the need for eyeglasses; however, people with toric IOLs should have less astigmatism and better vision without glasses than if a traditional IOL was used.

Presbyopia
The eye's ciliary muscle contracts, causing the eye's natural lens to thicken or change shape, which allows us to see objects up close. Presbyopia develops as we age, when our lens becomes less flexible and resists changing shape. With presbyopia, up-close focusing becomes more difficult. Learn more at http://www.geteyesmart.org.
